Ultrasonic level meter for dry drain monitoring. Real-time, precise measurement of water level, flow velocity and water discharge is critical in many hydrological applications.When they are mounted on existing infrastructure, there is very small amount of construction work required.

In case when dry drain or overflows should be monitored and action taken or alarm activated in case of water or any other liquid detection AI-ULM is ideal for the work. Reliable, non-contact, IP68, easy installed and with variety of communication or contact output interfaces will suit in all systems and applications.
